Police work is demanding and stressful, and police chiefs set the tone for the officers, detectives and other staff members in their department. They also serve as liaisons among the department, city officials and the public. To perform all of these duties, police chiefs must have excellent leadership skills. To develop these skills, police chiefs undergo extensive training, both regionally and through national organizations like the International Association of Chiefs of Police, which offers a range of courses specifically designed for police chiefs.
